13 v. MEMORANDUM OPINION AND ORDER 14 ANDREW M. SAUL, Commissioner of Social Security, 15 Defendant. 16

17 18 I. 19 BACKGROUND 20 Plaintiff Diane A. H. (“Plaintiff”) attended college for two or three years and 21 received a certificate to work as a dental assistant. Administrative Record (“AR”) 22 41, 191. From 1988 until 2013, she worked as a hospital data coordinator 23 collecting information about patient history and treatment from medical charts and 24 inputting the data into a laptop computer. AR 44–45, 192. She stopped working in 25 January 2013 when the hospital eliminated her position. AR 46, 191–92. As of 26 October 2018, she could drive a car, maintain a routine for performing self-care, 27 household chores, and meal preparation, do jigsaw puzzles, visit with friends, and 28 shop. AR 42–44. 1 In March 2016, Plaintiff applied for Title II Social Security Disability 2 Insurance Benefits (“DIB”), alleging that she became unable to work on January 1, 3 2014, due to various physical impairments and the mental impairments of 4 depression and anxiety. AR 19, 168–72, 190. On October 29, 2018, an 5 Administrative Law Judge (“ALJ”) conducted a hearing at which Plaintiff, who was 6 represented by counsel, appeared and testified, as did a vocational expert (“VE”). 7 AR 34–60. On November 30, 2018, the ALJ issued an unfavorable decision. AR 8 19–29. 9 The ALJ found that Plaintiff suffered from the severe, medically 10 determinable impairments of fibromyalgia, degenerative joint/disc disease of the 11 lumbar spine, and hepatitis. AR 21. The ALJ further found that Plaintiff’s 12 medically determinable mental impairment of depressive disorder was nonsevere, 13 because it caused only mild limitations in the four relevant areas of mental 14 functioning. AR 22–23. 15 The ALJ found that Plaintiff had a residual functional capacity (“RFC”) to 16 perform light work with the following additional restrictions: “[She] may not climb 17 ladders, ropes or scaffolds and may perform all other postural activities on an 18 occasional basis. [She] must avoid concentrated exposure to temperature extremes, 19 vibration and hazards, such as unprotected heights and dangerous machinery.” AR 20 24. Based on the RFC analysis and the VE’s testimony, the ALJ found that 21 Plaintiff could do her past relevant work as a medical records data clerk, Dictionary 22 of Occupational Titles (“DOT”) 245.362-010.1 AR 28–29. The ALJ concluded 23 that Plaintiff was not disabled from January 1, 2014, through the date of his 24 decision. AR 29. 25 26

27 1 The ALJ’s decision inadvertently labels the medical records data clerk as 28 DOT 243.362-010. Compare AR 28, with id. 56, 74–75, 91–92. 1 II. 2 ISSUES PRESENTED 3 Issue One: Whether the ALJ’s step-two finding that Plaintiff suffered from 4 no severe mental impairment is supported by substantial evidence? 5 Issue Two: Whether the ALJ “erred by failing to include the mild mental 6 limitations in determining the RFC.” 7 (Dkt. 24, Joint Stipulation [“JS”] at 4.) 8 III. 9 SUMMARY OF THE MENTAL IMPAIRMENT EVIDENCE 10 In December 2014 through April 2016, mental status examinations by 11 Plaintiff’s primary care physicians were unremarkable. They invariably found her 12 to be alert, cooperative, and fully oriented, with normal speech and cognitive 13 function. AR 262, 268, 271, 283, 298, 364. On examination, anxiety and 14 depression symptoms were not present and she showed no signs of memory loss. 15 AR 271, 274, 286, 289, 291, 297, 363. 16 In October 2015, Plaintiff was referred to the Arthritis Medical Clinic for a 17 rheumatology evaluation. AR 306. Plaintiff complained of depression, stress, 18 anxiety, memory loss, and difficulty with concentration related to her fibromyalgia. 19 AR 306, 309. However, on examination, she was alert and fully oriented, with 20 appropriate affect and demeanor, intact memory, and good insight and judgment. 21 AR 307. Plaintiff was assessed with fibromyalgia and osteoarthritis. AR 307. 22 While Plaintiff continued to complain of depression and anxiety related to her 23 fibromyalgia from January through June 2016, mental status examination found her 24 alert and oriented, with appropriate affect and demeanor, intact recent and remote 25 memory, and good insight and judgment. AR 327, 337–38, 340. In August, 26 September, and October 2016, neurological examinations were unremarkable. AR 27 360, 371, 375. Plaintiff was neither diagnosed with depression or anxiety nor 28 referred for psychiatric treatment. 1 In August 2015, Anthony Benigno, Psy.D., a clinical psychologist, conducted 2 a complete psychological evaluation at the request of the Commissioner. AR 353– 3 58. Dr. Benigno reviewed the available medical records, obtained historical 4 information from Plaintiff, conducted a mental status examination, and performed a 5 battery of tests. AR 353. Plaintiff, who arrived early and alone for her 6 appointment, reported that she has had anxiety since 2006 and depression since 7 2011 but denied seeking or receiving any treatment aside from taking Cymbalta.2 8 AR 353, 357. During a typical day, Plaintiff watched television, gardened, and 9 read. At 354. She acknowledged being able to independently dress, bathe, 10 complete household chores, pay bills, use a telephone, shop, do laundry, make 11 meals, drive, and manage her own funds. AR 354. Plaintiff reported socializing 12 with neighbors and friends but did not get along well with her family. AR 354. 13 On examination, Plaintiff was alert, attentive, and cooperative. AR 355. She 14 “demonstrate[d a] willingness to complete tasks and appeared to be putting forth 15 [her] best effort.” AR 355. Plaintiff was oriented to person, but not to time, place, 16 and purpose of examination. AR 355. Her thoughts were coherent and logical, 17 with appropriate content. AR 355. Dr. Benigno found that Plaintiff’s current 18 intellectual functioning was in “the borderline range.” AR 355. Plaintiff’s mood 19 was dysthymic/anxious with restricted range of affect. AR 355. Her immediate, 20 recent, and remote memory were intact. AR 355. She demonstrated an adequate 21 attention span and was able to sustain concentration and work without distraction. 22 AR 355. While Dr. Benigno found that Plaintiff’s insight into her illness was poor, 23 her fund of knowledge and judgment for commonsense hypothetical events were 24 adequate. AR 355. 25 26 2 Cymbalta (duloxetine) is an antidepressant that is used to treat both major 27 depressive disorder and general anxiety disorder. (last visited 28 Nov. 25, 2020). 1 As for the test results, Plaintiff was in the “severely impaired range” on the 2 Trail Making Test, Parts A and B.3 AR 355–56. On the Wechsler Adult 3 Intelligence Scale, Plaintiff’s general intellectual functioning was in the “borderline 4 range.” AR 356. On the Wide Range Achievement Test, no indications of a 5 learning disability were found. AR 356. Dr. Benigno diagnosed “probable” 6 anxiety disorder, depressive disorder, and borderline intellectual functioning, and 7 assessed a Global Assessment of Functioning (“GAF”) score of 75.4 He opined that 8 Plaintiff would have no difficulty understanding, remembering, and carrying out 9 short, simplistic instructions or managing her own finances. AR 357. He further 10 opined that Plaintiff would have mild difficulty understanding, remembering, and 11 carrying out detailed and complex instructions; making simplistic work-related 12 decisions without special supervision; responding to change in a workplace setting; 13 maintaining persistence and pace in a normal workplace setting; or interacting with

14 3 “The Trail Making Test is a neuropsychological test of visual attention and 15 task switching. It consists of two parts in which the subject is instructed to connect a set of 25 dots as quickly as possible while still maintaining accuracy. The test can 16 provide information about visual search speed, scanning, speed of processing, 17 mental flexibility, as well as executive functioning. It is sensitive to detecting cognitive impairment associated with dementia, for example, Alzheimer’s disease.” 18 (last visited Nov. 25, 2020) 19 (footnote omitted). 20 4 “A GAF score is a rough estimate of an individual’s psychological, social, and occupational functioning used to reflect the individual’s need for treatment.” 21 Vargas v. Lambert, 159 F.3d 1161, 1164 n.2 (9th Cir. 1998). The GAF includes a 22 scale ranging from 0–100 and indicates a “clinician’s judgment of the individual’s overall level of functioning.” American Psychiatric Association, Diagnostic and 23 Statistical Manual of Mental Disorders 32 (4th ed. text rev. 2000) (hereinafter 24 DSM–IV). According to DSM–IV, a GAF score of 71–80 suggests that if symptoms are present, they are “transient and expectable reactions to psychosocial 25 stressors” and cause “no more than slight impairment in social, occupational or 26 school functioning.” Id. 34. “Although GAF scores, standing alone, do not control determinations of whether a person’s mental impairments rise to the level of a 27 disability (or interact with physical impairments to create a disability), they may be 28 a useful measurement.” Garrison v. Colvin, 759 F.3d 995, 1003 n.4 (9th Cir. 2014). 1 appropriately with supervisors, coworkers, and peers on a consistent basis. AR 2 357. Finally, Dr. Benigno opined that Plaintiff would have moderate difficulty 3 complying with job rules such as safety and attendance. AR 357. 4 In September 2016, Harvey Bilik, Psy.D., a state agency consultant, reviewed 5 the medical record and concluded that Plaintiff had mild restriction of activities of 6 daily living, mild difficulties in maintaining social functioning, and mild difficulties 7 in maintaining concentration, persistence, or pace. AR 68–69. Dr. Bilik opined 8 that “[Plaintiff] can understand and remember simple and detailed—but perhaps not 9 complex—instructions. [She] can carry out simple and detailed—but perhaps not 10 complex—instructions over the course of a normal workweek. [Plaintiff] can 11 interact appropriately with others. [She] can adapt despite any limitations in this 12 domain.” AR 74. 13 From October 2016 through July 2018, mental status examinations were 14 normal—Plaintiff was alert, cooperative, and fully oriented with an appropriate 15 affect and intact memory. AR 417, 420, 423, 427, 428, 430, 432, 436, 439, 442, 16 444, 498. In November 2016, January 2017, and July 2017, Plaintiff exhibited no 17 signs of depression or anxiety. AR 436, 439, 446, 497. In March 2017, Plaintiff’s 18 certified nurse practitioner did not assess any mental impairments related to 19 Plaintiff’s fibromyalgia. AR 362, 505. 20 In December 2016, R. Waranch, Ph.D., a state agency consultant, reviewed 21 the medical record and concluded that Plaintiff had a mild restriction of activities of 22 daily living but moderate difficulties in maintaining social functioning and in 23 maintaining concentration, persistence, or pace. AR 85. Dr. Waranch opined that: 24 [Plaintiff] is capable of understanding, remembering and carrying out 25 short, simplistic instructions but would have difficulty with more 26 detailed and complex instructions. [She] would be able to interact 27 with the public, supervisors and coworkers if contacts were 28 intermittent and not prolonged. [Plaintiff] would be capable of 1 completing a workday/workweek without interruption and working at 2 a consistent pace. [She] is capable of adapting to changes and 3 pressures in the workplace related to performing simple tasks. 4 AR 91. 5 IV. 6 DISCUSSION 7 A. Plaintiff Did Not Have a Severe Mental Impairment. 8 Plaintiff contends that the ALJ erred at step two in failing to find that her 9 mental impairment was severe. (JS at 4–14, 19.) By its own terms, the evaluation 10 at step two is a de minimis test intended to weed out the most minor of 11 impairments. See Bowen v. Yuckert, 482 U.S. 137, 153–54 (1987) (O’Connor, J., 12 concurring); Edlund v. Massanari, 253 F.3d 1152, 1158 (9th Cir. 2001) (“We have 13 defined the step-two inquiry as a de minimis screening device to dispose of 14 groundless claims.”). An impairment is not severe only if the evidence establishes 15 a slight abnormality that has only a minimal effect on an individual’s ability to 16 work. Smolen, 80 F.3d at 1290; see 20 C.F.R. § 404.1520a(d)(1) (“If we rate the 17 degrees of your limitation as ‘none’ or ‘mild,’ we will generally conclude that your 18 impairment(s) is not severe, unless the evidence otherwise indicates that there is 19 more than a minimal limitation in your ability to do basic work activities.”) 20 The ALJ’s step-two finding of no severe mental impairment was supported 21 by substantial evidence. The ALJ acknowledged that Plaintiff’s depressive disorder 22 was a medically determinable impairment. AR 22. Nevertheless, the ALJ found 23 that at most Plaintiff had only a mild limitation in understanding, remembering, and 24 applying information, and in concentrating, persisting, and maintaining pace. AR 25 22. While Plaintiff endorsed memory loss, brain fog, and difficulty with 26 concentration, neurological examinations by Plaintiff’s treating physicians found no 27 28 1 abnormalities.5 AR 22 (citing AR 360, 363, 442, 444). While Dr. Benigno found 2 deficits in Plaintiff completing the Trail Making Test, her immediate, recent, and 3 remote memories were intact, and Dr. Benigno concluded that Plaintiff had 4 adequate memory, fund of knowledge, attention, and concentration. AR 22, 355– 5 56. The ALJ next found that at most Plaintiff had only a mild limitation in 6 interacting with others. AR 22. Plaintiff did not allege any problems with getting 7 along with others, and at her medical appointments, and the consultative 8 examination, her doctors routinely assessed Plaintiff as “cooperative.” AR 22 9 (citing AR 268, 271, 283, 355, 417, 423, 430, 432). Finally, the ALJ found that at 10 most Plaintiff had mild limitation in adapting or managing herself. AR 22. 11 Therefore, the ALJ concluded that Plaintiff’s mental impairment was nonsevere. 12 AR 23. 13 Plaintiff failed to demonstrate that her depression or anxiety caused more 14 than minimal limitations on her ability to perform basic mental work activities. 15 Plaintiff does not identify—and this Court cannot locate—any evidence from her 16 treating physicians that contradicts the ALJ’s findings. Instead, Plaintiff contends 17 that the ALJ should have adopted Dr. Benigno’s opinion that Plaintiff had moderate 18 difficulty in complying with work rules such as safety and attendance. (JS at 12– 19 13.) The ALJ gave Dr. Benigno’s opinion “significant weight” but rejected this one 20 moderate limitation because Dr. Benigno did not explain why Plaintiff would have 21 difficulties in this one area and “finding no evidence of [Plaintiff’s] failing to meet 22 medical, social or other obligations on the record.”6 AR 23. Plaintiff argues that it 23 5 The ALJ partially rejected Plaintiff’s subjective symptom statements, 24 finding her reported pain levels and alleged functional limitations inconsistent with 25 the medical evidence, the clinical findings, and Plaintiff’s “retained independence and robust activities of daily living.” AR 25–26, 28. Plaintiff does not contest the 26 ALJ’s partial rejection of her subjective statements. 27 6 For claims filed before March 27, 2017, such as Plaintiff’s, the ALJ must 28 explain the weight given to medical source opinions. 20 C.F.R. § 404.1527(c). 1 “appear[s] that [ ] Dr. Benigno’s opinion was based in part on the Trail Making 2 Test.” (JS at 12.) However, there is nothing in Dr. Benigno’s opinion to support 3 Plaintiff’s mere speculation. Indeed, Dr. Benigno emphasized that Plaintiff drove 4 herself and arrived alone and early to the examination. AR 353, 357. Plaintiff does 5 not identify what aspects of the Trail Making Test implicate either safety or 6 attendance. Further, as the ALJ noted, Dr. Benigno’s moderate limitation 7 assessment in this one area was inconsistent with assigning Plaintiff a GAF score of 8 75, which suggests that if symptoms are present, they are “transient and expectable 9 reactions to psychosocial stressors” and cause “no more than slight impairment in 10 social, occupational or school functioning.” DSM-IV 34; see AR 22–23; see also 11 Schamel v. Astrue, No. 4:09CV1729, 2011 WL 864975, at *15, 2011 U.S. Dist. 12 LEXIS 24418, at *42 (E.D. Mo. Mar. 10, 2011) (finding that a GAF score of 80 13 “reflects transient, non-severe symptoms”). 14 Plaintiff also asserts that because the ALJ gave “some weight” to Dr. Bilik’s 15 opinion, the ALJ should have adopted Dr. Bilik’s multiple moderate limitations 16 which “represents a severe impairment.” (JS at 9.) In Dr. Bilik’s mental RFC 17 assessment, he found that Plaintiff was moderately limited in her ability to 18 understand, remember, and carry out detailed instructions; maintain attention and 19 concentration for extended periods; sustain an ordinary routine without special 20 supervision; complete a normal workday and workweek without interruptions from 21 psychologically based symptoms and to perform at a consistent pace without an 22 unreasonable number and length of rest periods; respond appropriately to changes 23 in the work setting; and set realistic goals or make plans independently of others. 24 AR 72–73. But the ALJ merely gave “some weight to the assessment by Dr. 25 Bilik . . . that [Plaintiff’s] depression and anxiety disorders were non-severe.” AR 26 23; see AR 68 (Dr. Bilik finding that Plaintiff had only mild restriction of activities 27 of daily living, difficulties in maintaining social functioning, and difficulties in 28 maintaining concentration, persistence, or pace). 1 The weight to be afforded the opinions of nontreating physicians, such as Dr. 2 Bilik, “depends ‘on the degree to which they provide supporting explanations for 3 their opinions.’” Ryan v. Comm’r of Soc. Sec., 528 F.3d 1194, 1201 (9th Cir. 4 2008) (quoting 20 C.F.R. § 404.1527(d)(3)); see also Holohan v. Massanari, 246 5 F.3d 1195, 1202 (9th Cir. 2001) (“Generally, a treating physician’s opinion carries 6 more weight than an examining physician’s, and an examining physician’s opinion 7 carries more weight than a reviewing [(nonexamining)] physician’s.”); accord 8 Garrison v. Colvin, 759 F.3d 995, 1012 (9th Cir. 2014). Here, the only evidence of 9 any mental limitations was from Dr. Benigno’s consultative examination.7 As 10 discussed above, the ALJ supported his decision giving Dr. Benigno’s opinion 11 significant weight with substantial evidence. “[T]he ALJ is the final arbiter with 12 respect to resolving ambiguities in the medical evidence.” Tommasetti v. Astrue, 13 533 F.3d 1035, 1041 (9th Cir. 2008). On this record, the ALJ reasonably rejected 14 Dr. Bilik’s opinion to the extent that it indicated any moderate functional 15 limitations. 16 Even if the ALJ should have adopted Dr. Bilik’s opinion as the proper 17 interpretation of Dr. Benigno’s examination, the error was harmless. See Burch v. 18 Barnhart, 400 F.3d 676, 679 (9th Cir. 2005) (“A decision of the ALJ will not be 19 reversed for errors that are harmless.”). Plaintiff argues that Dr. Bilik’s opinion that 20 Plaintiff suffers from moderate limitations in performing complex tasks precludes 21 her from doing any work that requires reasoning level 4, including her past relevant 22 work. (JS at 10.) The DOT addresses a job’s level of simplicity by assigning a 23 general educational development (“GED”) rating for reasoning development. The 24 7 Dr. Bilik cited two examinations by Plaintiff’s treating rheumatologist as 25 evidence of “active depression, stress/anxiety, mood swing.” AR 67. However, 26 these assessments were subjective symptom statements made by Plaintiff, and in a psychiatric examination done on the same date, the rheumatologist found Plaintiff 27 alert and oriented, with appropriate affect and demeanor, intact recent and remote 28 memory, and good judgment and insight. AR 322, 337–38. 1 DOT’s GED reasoning scale ranges from level 1 (lowest) to level 6 (highest). 2 Reasoning level 4 requires workers to “apply principles of rational systems to solve 3 practical problems and deal with a variety of concrete variables in situations where 4 only limited standardization exists; interpret a variety of instructions furnished in 5 written, oral, diagrammatic, or schedule form.” DOT Appendix C. Examples of 6 rational systems include “bookkeeping, internal combustion engines, electric wiring 7 systems, house building, farm management, and navigation.” Id. Other jobs that 8 require reasoning level 4 include real estate agent (DOT 250.357-018), billing clerk 9 (DOT 214.362-042), inspector (DOT 806.264-014), residential manager (DOT 10 186.167-018), and wedding consultant (DOT 299.357-018).8 11 Dr. Bilik did not use the DOT’s GED reasoning levels to define Plaintiff’s 12 functional limitations, but he did distinguish between simple, detailed, and complex 13 tasks. AR 74. He found that Plaintiff could do “simple and detailed” tasks but 14 “perhaps not” complex tasks. AR 74; cf. AR 357 (Dr. Benigno opining that 15 Plaintiff would have only mild difficulty with both detailed and complex 16 instructions). The ALJ could reasonably interpret Dr. Bilik’s opinion as referring to 17 jobs with reasoning levels 1 or 2 as “simple,” jobs with reasoning levels 3 or 4 as 18 “detailed,” and jobs with reasoning levels 5 or 6 as “complex.” The DOT does not 19 use the work “complex” to describe level 4 reasoning. Level 4 reasoning involves 20 8 In contrast, reasoning level 3 is defined as the ability to follow written, oral, 21 or diagrammatic instructions and to deal with problems involving several variables 22 from a standardized situation. DOT Appendix C. Driving jobs often require reasoning level 3. See, e.g., sales route driver (DOT 292.353-010), taxi driver 23 (DOT 913.463-018), light truck driver (DOT 906.683-022), and heavy truck driver 24 (DOT 905.663-014). Reasoning level 5 requires workers to “[a]pply principles of logical or scientific thinking to define problems, collect data, establish facts, and 25 draw valid conclusions. Interpret an extensive variety of technical instructions in 26 mathematical or diagrammatic form. Deal with several abstract and concrete variables.” DOT Appendix C. Jobs requiring reasoning level 5 include loan officer 27 (DOT 186.267-018), land agent (DOT 186.117-058), and director of rehabilitation 28 services (DOT 076.117-010). 1 concrete rather than abstract variables with some standardization, albeit limited. 2 This kind of reasoning should not be described with the highest available 3 descriptor, i.e., “complex.” Thus, even fully crediting Dr. Bilik’s opinions would 4 not establish that Plaintiff could not do work that requires level 4 reasoning. 5 Indeed, upon initial review, the Commissioner concluded that Dr. Bilik’s mental 6 functional assessment would not preclude Plaintiff from performing her past 7 relevant work. AR 66, 75; see AR 104 (“Although you have been experiencing 8 some anxiety and depression, there are no indications that this imposes major 9 limitations upon your ability to think, communicate, and follow basic instructions 10 or to function adequately in your usual activities. … [T]hese limitations do not 11 prevent you from performing work you have done in the past ….”). 12 Plaintiff further argues that Dr. Waranch’s opinion “confirms the presence of 13 a severe mental impairment.” (JS at 13.) Dr. Waranch opined that Plaintiff 14 suffered from multiple moderate impairments and could not perform detailed or 15 complex tasks. AR 89–91. The ALJ gave Dr. Waranch’s opinion “little weight,” 16 finding that it was “based, at least in part, on his finding that [Plaintiff] suffered 17 from a neurocognitive disorder, that [Plaintiff] neither alleged, nor that was 18 diagnosed by any of [Plaintiff’s] treating physicians or the psychological 19 consultative examiner, after administering a barrage of psychometric assessments.” 20 AR 23; see AR 84 (Dr. Wallach stating that Plaintiff has a “Neurocog dis”). As the 21 ALJ noted, not only is there no such diagnosis by any of Plaintiff’s treating 22 physicians, but the consultative examiner’s interpretation of his own testing is 23 deserving of significant weight. AR 23. Indeed, Dr. Benigno’s “opinion alone 24 constitutes substantial evidence, because it rests on his own independent 25 examination of [Plaintiff].” Tonapetyan v. Halter, 242 F.3d 1144, 1149 (9th Cir. 26 2001); see Sandgathe v. Chater, 108 F.3d 978, 980 (9th Cir. 1997) (“Reports of 27 consultative physicians called in by the Commissioner may serve as substantial 28 evidence.”) (citation omitted); cf. Orn v. Astrue, 495 F.3d 625, 632 (9th Cir. 2007) 1 (ALJ errs in relying on examining physician who does not conduct his own 2 examination but instead relies “on the same clinical findings as a treating 3 physician[ ] but differs only in his or her conclusions”). 4 B. Plaintiff’s Mild Mental Limitations Did Not Limit Her Ability To Work. 5 Plaintiff contends that even assuming her mental limitations were only mild, 6 they should have been included in the RFC. (JS at 20–23, 25–26.) In assessing a 7 claimant’s RFC, an ALJ must consider the combined effect of all of the claimant’s 8 medically determinable physical and mental impairments, whether severe or 9 nonsevere. 20 C.F.R. §§ 404.1545(a)(2), 416.945(a)(2); see SSR 96-8p, at *5 (“In 10 assessing RFC, the adjudicator must consider limitations and restrictions imposed 11 by all of an individual’s impairments, even those that are not ‘severe.’”); accord AR 12 20 (ALJ noting that in making his RFC finding, he “must consider all of 13 [Plaintiff’s] impairments, including impairments that are not severe”). “The RFC 14 therefore should be exactly the same regardless of whether certain impairments are 15 considered ‘severe’ or not.” Buck v. Berryhill, 869 F.3d 1040, 1049 (9th Cir. 16 2017). 17 Here, the ALJ considered Plaintiff’s depression, which the ALJ found to be a 18 medically determinable mental impairment, in assessing her RFC. He 19 acknowledged that Plaintiff testified to brain fog, problems concentrating, fatigue, 20 and lethargy. AR 25, 27. Nevertheless, the ALJ emphasized that Plaintiff’s 21 physicians reported she was alert and understood her various diagnoses, regularly 22 presented in “no acute distress,” and readily communicated her symptoms. The 23 ALJ also noted that medical records indicated Plaintiff had a “high level of 24 functioning,” drove herself to medical appointments and social visits, and managed 25 self-care tasks and household and outside chores without assistance. AR 25. As 26 discussed above, Plaintiff has not identified any evidence from her treating sources 27 that implicated her ability to perform basic mental work activities. “The mere 28 existence of an impairment is insufficient proof of a disability.” Matthews v. 1 || Shalala, 10 F.3d 678, 680 (9th Cir. 1993); see Key v. Heckler, 754 F.2d 1545, 1549 2 || (9th Cir. 1985) (“The mere diagnosis of an impairment ... is not sufficient to 3 || sustain a finding of disability.””); accord Lundell v. Colvin, 553 F.
